A chassis and a method of manufacturing a chassis of an information handling system are disclosed. The chassis includes a carbon-fiber composite and a plurality vents of formed in the carbon-fiber composite. Each of the plurality of vents is a channel extending through the carbon-fiber composite.

TECHNICAL FIELD

The present disclosure relates generally to information handlingsystems, and more particularly to a vent area for a carbon-fiber chassisof an information handling system.

BACKGROUND

As the value and use of information continues to increase, individualsand businesses seek additional ways to process and store information.One option available to users is information handling systems. Aninformation handling system generally processes, compiles, stores,and/or communicates information or data for business, personal, or otherpurposes thereby allowing users to take advantage of the value of theinformation. Because technology and information handling needs andrequirements vary between different users or applications, informationhandling systems may also vary regarding what information is handled,how the information is handled, how much information is processed,stored, or communicated, and how quickly and efficiently the informationmay be processed, stored, or communicated. The variations in informationhandling systems allow for information handling systems to be general orconfigured for a specific user or specific use such as financialtransaction processing, airline reservations, enterprise data storage,or global communications. In addition, information handling systems mayinclude a variety of hardware and software components that may beconfigured to process, store, and communicate information and mayinclude one or more computer systems, data storage systems, andnetworking systems.

An information handling system may include a chassis, which serves as aframe or base for the physical components of the system. The componentsof the information handling system may be positioned on or enclosedwithin the chassis. An important consideration in the operation of aninformation handling system is cooling the components enclosed withinthe chassis. Excessive heat within the chassis can harm the operation ofthe components of the information handling system. Accordingly, airmovers (e.g., cooling fans and blowers) have often been used inconjunction with vent areas to dissipate or evacuate heat generated bythe components.

DETAILED DESCRIPTION

Preferred embodiments and their advantages are best understood byreference to FIGS. 1-10, wherein like numbers are used to indicate likeand corresponding parts.

For the purposes of this disclosure, an information handling system mayinclude any instrumentality or aggregate of instrumentalities operableto compute, calculate, determine, classify, process, transmit, receive,retrieve, originate, switch, store, display, communicate, manifest,detect, record, reproduce, handle, or utilize any form of information,intelligence, or data for business, scientific, control, or otherpurposes. For example, an information handling system may be a personalcomputer (e.g., desktop or laptop), tablet computer, mobile device(e.g., personal digital assistant (PDA) or smart phone), server (e.g.,blade server or rack server), a network storage device, or any othersuitable device and may vary in size, shape, performance, functionality,and price. The information handling system may include random accessmemory (RAM), one or more processing resources such as a centralprocessing unit (CPU) or hardware or software control logic, ROM, and/orother types of nonvolatile memory. Additional components or theinformation handling system may include one or more disk drives, one ormore network ports for communicating with external devices as well asvarious input and output (I/O) devices, such as a keyboard, a mouse,touchscreen and/or a video display. The information handling system mayalso include one or more buses operable to transmit communicationbetween the various hardware components.

An information handling system chassis may be constructed of manydifferent materials, including, for example, a multi-layeredcarbon-fiber composite. Carbon-fiber composite may be used because ofits high strength-to-weight ratio. For example, carbon-fiber compositesmay be used to provide a light-weight, durable chassis for a laptopcomputer, tablet computer, or mobile device. Additionally, carbon-fibercomposites may be used for the chassis of a desktop computer, server, ornetwork storage device.

An important consideration in the operation of an information handlingsystem is cooling the interior of the chassis. This may be accomplishedthrough the use of air movers (e.g., cooling fans and blowers) inconjunction with vents, which permit air circulation through thechassis. Forming vents in a carbon-fiber chassis may, however, be moredifficult than in a chassis of another material. For example, mostmetals are formed from crystalline structures, which have naturalfracture lines. When machined, the crystalline structures tend to breakaway from the remainder of the material in somewhat uniform bits. Acarbon-fiber composite, on the other hand, is formed from multiplelayers of a carbon-fiber material, each of which includes manyindividual carbon fibers. When a carbon-fiber composite is machined,individual carbon fibers may be severed along the edge of the machinedhole or slot, creating a rough, or ragged, surface as compared to thesurfaces of a slot or hole machined in a metal chassis.

In the context of a vent formed in a carbon-fiber composite, these roughsurfaces may result in the turbulent flow of air through the vents,which may reduce the efficiency of the vents. Additionally, when aportion of the individual carbon fibers are severed, the carbon-fibercomposite along the edge of the vents may be weakened, which may resultin cracking or crumbling of the material between or adjacent to thevents. To reduce the impact of these issues, vents may be formed asmicro-channels in the carbon-fiber composite. Where the vents are formedas micro-channels, each vent may be aligned with a single carbon fiber;which may reduce the number of fibers that are severed during theformation of the vents. Embodiments in which the vents are formed asmicro-channels in the carbon-fiber composite are discussed in detail inconjunction with FIGS. 4-8. Alternatively, machining vents in thecarbon-fiber composite may be avoided altogether by forming the vents ina non-carbon fiber insert, which may be bonded to the chassis.Embodiments in which the vents are formed in an insert are discussed indetail in conjunction with FIGS. 9 and 10.

A multi-layered carbon-fiber composite used to construct the chassis ofan information handling system may, in some embodiments, have betweenthree and ten layers, including both polymer and carbon-fiber layers.For example, FIG. 1 illustrates a cross-section of a multi-layeredcarbon-fiber composite 100, which may include a polymer layer 120sandwiched between a first carbon-fiber layer 110A and a secondcarbon-fiber layer 110B. The carbon-fiber layers 110 may beunidirectional carbon-fiber cloth impregnated with a polymer, such asepoxy, polyester, vinyl ester, or nylon. In certain embodiments,carbon-fiber layers 110 may include a carbon-fiber loading of less thanthirty percent. Polymer layer 120, which may be included to providerigidity, may be a polymer such as epoxy, polyester, vinyl ester, ornylon.

As another example, FIG. 2 illustrates a cross-section of multi-layeredcarbon-fiber composite 200 including nine layers. As with composite 100,the outermost layers 210A and 210E of composite 200 may be carbon-fiberlayers. Composite 200 may include alternating carbon-fiber layers(layers 210A, 210B, 210C, 210D, and 210E) and polymer layers (layers220A, 220B, 220C, and 220D). Carbon-fiber layers 210 may beunidirectional carbon-fiber cloth impregnated with a polymer, such asepoxy, polyester, vinyl ester, or nylon. In certain embodiments,carbon-fiber layers 210 may include a carbon-fiber loading of less thanthirty percent. Polymer layers 220 may be a polymer such as epoxy,polyester, vinyl ester, or nylon.

As a further example, FIG. 3 illustrates an alternative embodiment of amulti-layered carbon-fiber composite 300. Like composites 100 and 200,composite 300 may include carbon-fiber layers 310 and polymer layers320. The outermost layers 310A and 310F may be carbon-fiber layers. Incertain embodiments, carbon-fiber layers 310 may include a carbon-fiberloading of less than thirty percent. Polymer layers 320 may be a polymersuch as epoxy, polyester, vinyl ester, or nylon. The interior layers ofcomposite 300 may alternate between a single polymer layer 320 and twocarbon-fiber layers 310. Although not illustrated, a multi-layeredcarbon-fiber composite used to form a chassis may include othervariations of alternating carbon-fiber and polymer layers. Regardless ofthe number of layers included in the composite, the overall thickness ofa multi-layer carbon-fiber composite used for form a chassis may, insome embodiments, be between 0.5 millimeters and 2.0 millimeters.

FIG. 4 illustrates a portion of a chassis 410 in which vents have beenformed in the chassis itself. Chassis 410 may include a vent area 420including a plurality of vents 430. Vents 430 may be a series of slotsor holes in a surface or wall of chassis 410. Air may flow through vents430 via forced or natural convection. The dimensions of vent area 420may depend on the spacing and size of vents 430.

In some embodiments, vents 430 may be organized in substantiallyparallel rows, as shown in FIG. 4, with a center-to-center spacing (orpitch) of approximately forty microns. In other embodiments, vents 430may be more or less widely dispersed over the surface of chassis 410. Asdiscussed above, each vent 430 may be aligned with a single carbon fiberto reduce the number of fibers that may be severed during the formationof the vents 430. Additionally, vents 430 may be sized to prevent dustparticles, which may be between twenty and thirty microns in diameter,from entering chassis 410 through vents 430. Thus, to prevent dust fromentering chassis 410, vents 430 may have a width or diameter less thantwenty microns. Vents 430 with a width or diameter less than twentymicrons may also be desirable because vents 430 of this size may notvisible to the human eye, which may be unable to detect structuresand/or objects smaller than approximately fifty microns.

Vents 430 may be formed by laser drilling (which may also be referred toas laser ablation), chemical etching, and/or gradient stamping (e.g.,the use of an array of conical cutting elements to puncture a givenmaterial, thereby creating a plurality of holes). These methods mayresult in vents 430 with substantially smoother surfaces than thoseproduced through traditional machining processes.

In some embodiments, which are discussed in further detail inconjunction with FIGS. 5 and 6, vents 430 may be conical micro-channelsextending through chassis 410. In other embodiments, which are discussedin further detail in conjunction with FIGS. 7-8, vents 430 may becylindrical micro-channels extending through chassis 410.

FIG. 5 illustrates a cross section of a portion of chassis 410 includingconical vents 530 formed in chassis 410. The portion of chassis 410shown in FIG. 5 includes two vents 530. Arrow A may represent air flowthrough vents 530 from the interior of chassis 410 to the exterior ofchassis 410. To prevent dust from entering chassis 410, the smallestdiameter (d1) of conical vents 530 may be less than twenty microns. Toreduce friction between the walls of vents 530 and air flowing throughvents 530, the ratio between the thickness (t) of the composite used toform chassis 410 and the maximum diameter (d2) of vents 530 may begreater than or equal to one hundred. Thus, a chassis 410 formed of amaterial with a thickness of two millimeters may include vents 530 witha maximum diameter of less than or equal to twenty microns, while achassis 410 formed of a material with a thickness of one millimeters mayinclude vents 530 with a maximum diameter of less than or equal to tenmicrons. As discussed above, in some embodiments, vents 530 may have awith a center-to-center spacing, also referred to as pitch (p), ofapproximately forty microns.

FIG. 6 illustrates an example method 600 of forming a chassis includingconical vents formed in the multi-layered carbon fiber composite of thechassis. The method may begin at step 610. At step 610, the carbon-fiberlayers may be bonded to form a multi-layered carbon-fiber composite. Thecarbon fiber layers may be laminated using a polymer, such as epoxy,polyester, vinyl ester, or nylon. The polymer used to laminate thecarbon fiber layers may form the polymer layers of the carbon-fibercomposite. When the carbon-fiber composite has been formed, the methodmay proceed to step 620.

At step 620, the desired size and position of the vents may bedetermined. As discussed above, each vent may be aligned with a singlecarbon fiber to reduce the number of fibers that may be severed duringthe formation of the vents. Additionally, vents may be sized to preventdust from entering the chassis through the vents and/or sized so as tobe undetectable by a human eye. At step 630, the vents may be formed inthe carbon-fiber composite. As discussed above, the vents may be formedby laser drilling, chemical etching, and/or gradient stamping.

As discussed above, vents may also be formed as cylindricalmicro-channels extending through chassis 410. FIG. 7 illustrates across-section of a portion of chassis 410 includes cylindrical vents730. The portion of chassis 410 shown in FIG. 7 includes two vents 730.Arrow A may represent air flow through vents 730 from the interior ofchassis 410 to the exterior of chassis 410. To prevent dust fromentering chassis 410, the diameter (d) of vents 730 may be less thantwenty microns. To reduce friction between the walls of vents 730 andair flowing through vents 730, the ratio between the thickness (t) ofthe composite used to form chassis 410 and the diameter (d) of vents 730may be greater than or equal to one hundred. Thus, a chassis 410 formedof a material with a thickness of two millimeters may include vents 730with a maximum diameter of less than or equal to twenty microns, while achassis 410 formed of a material with a thickness of one millimeters mayinclude vents 730 with a maximum diameter of less than or equal to tenmicrons.

Unlike conical vents 530 shown in FIG. 5, which have a center axisoriented approximately perpendicular to an interior or exterior surfaceof chassis 410, cylindrical vents 730 may have a center axis 735oriented less than ninety degrees from an interior surface 740 ofchassis 410. The angle between center axis 735 of and interior surface740 may be represented by the angle α, which is shown in FIG. 7.Cylindrical vents 730 may be oriented in this manner to aid inpreventing dust particles from entering chassis 410. For example, a dustparticles that is oblong in shape may enter chassis 410 through conicalvents 530 so long as the smallest diameter of the dust particle is lessthan twenty microns. The same oblong dust particle may, however, not beable to enter chassis 410 through cylindrical vents 730 without rotatingor changing direction. Thus, the orientation of vents 730 may aid inpreventing dust particles from entering chassis 410.

FIG. 8 illustrates an example method 800 of forming cylindrical vents ina multi-layered carbon-fiber composite. To achieve the desiredorientation of the vents with respect to an interior or exterior surfaceof chassis 410, holes corresponding to each vent may be formed in eachcarbon-fiber layer of the multi-layered composite before the layers arebonded. The layers may then be aligned such that the center axis of eachhole in a carbon-fiber layer is offset from the center-axis of each holein an adjacent layer. By offsetting the holes in each layer, acylindrical vent with a center axis oriented less than ninety degreesfrom an interior surface of chassis 410 may be formed.

The method 800 may begin at step 810. At step 810, the desired size andorientation of the vents may be determined. Based on the desiredorientation of the center axis of the vents, an offset for the holes maybe calculated. In some embodiments, the holes may be offset such thatthe holes in a particular layer overlap the corresponding holes in anadjacent layer by at least thirty percent. In other embodiments, theholes may be offset such that the holes in a particular layer overlapthe corresponding holes in an adjacent layer by not more than seventypercent. Where the holes in adjacent layers have an overlap of seventypercent, the angle α may be greater than if the holes in adjacent layershave an overlap of thirty percent. Once the desired size and orientationof the vents is determined, the method may proceed to step 620.

At step 620, the holes corresponding to the cylindrical vents may beformed in the carbon-fiber layers of the multi-layered carbon-fibercomposite. This step may occur before the layers of the multi-layeredcarbon-fiber composite are bonded. As discussed above, the holescorresponding to the vents may be formed by laser drilling, chemicaletching, and/or gradient stamping. After the holes corresponding to thevents are formed, the method may proceed to step 630.

At step 630, the layers of the multi-layered carbon-fiber composite maybe aligned such that the holes in each layer have the desired offsetrelative to the holes in adjacent layers. As discussed above, in someembodiments, the holes may be offset such that the holes in a particularlayer overlap the corresponding holes in an adjacent layer by at leastthirty percent. In other embodiments, the holes may be offset such thatthe holes in a particular layer overlap the corresponding holes in anadjacent layer by not more than seventy percent. Once the layers havebeen aligned, the method may proceed to step 640. At step 640, thelayers may be bonded to form a multi-layered carbon-fiber composite. Insome embodiments, the carbon fiber layers may be laminated using apolymer, such as epoxy, polyester, vinyl ester, or nylon. The polymerused to laminate the carbon fiber layers may form the polymer layers ofthe carbon-fiber composite.

As discussed above, machining vents directly in the carbon-fibercomposite of a chassis may be avoided altogether by forming the vents ina non-carbon fiber insert, which may be bonded to the chassis. FIG. 9illustrates such an embodiment. Chassis 910 may include a vent area 920formed as an insert and bonded to chassis 910. Vent area insert 920 maybe received by cutout 915, which may extend through chassis 910. Cutout915 may be formed using traditional machining methods or, as discussedabove with respect to the formation of vents 430, through the use oflaser drilling, chemical etching, and/or gradient stamping.

Vent area insert 920 may be formed of a glass-filled nylon,polycarbonate, metal, or other material that may be bonded to themulti-layered carbon-fiber composite used to form chassis 910. Vent areainsert 920 may include a plurality of vents 930, which may be a seriesof cylindrical or conical micro-channels in vent area insert 920. Thedimensions of vent area insert 920 may depend on the spacing and size ofvents 930. As discussed above, vents 930 may have a width or diameter ofless than twenty microns to prevent dust from entering chassis 910through vents 930. Additionally, as discussed above with respect tovents 530 and vents 730, vents 930 may have a center-to-center spacing,or pitch (p), of approximately forty microns or may be more or lesswidely dispersed. Vents 930 may be formed using traditional machiningmethods or, as discussed above with respect to the formation of vents530 and 730, vents 930 may be formed through the use of laser drilling,chemical etching, and/or gradient stamping.

Vent area insert 920 may be coupled to chassis 910 using an insertmolding machine. For example, the multi-layered carbon-fiber compositeof chassis 910, together with vent area insert 920, may be placed in aninsert molding machine and bonded using a polymer resin.

FIG. 10 illustrates an example method 1000 of forming a multi-layeredcarbon-fiber chassis including a vent area insert. The method 1000 maybegin at step 1010. At step 1010, the desired shape, size, and layout ofthe vents in the vent area may be determined. As discussed above, ventsmay be a conical or cylindrical micro-channels extending through thematerial of the vent area insert. The vents may be sized to prevent dustfrom entering the chassis through the vents and/or sized so as to beundetectable by a human eye. Additionally, as discussed above, the ventsmay be arranged with a center-to-center spacing (or pitch) ofapproximately forty microns, or may be more or less widely dispersed.Once the desired shape, size, and layout of the vents is determined, themethod may proceed to step 1020.

At step 1020, the dimensions of the vent area insert may be determined.As discussed above, the dimensions of the vent area insert may depend onthe spacing and size of the vents. After the dimensions of the vent areainsert have been determined, the method may proceed to step 1030. Atstep 1030, the vent area insert may be created and the vents may beformed in the material of the vent area insert. As discussed above, thevent area insert may be formed of a glass-filled nylon, polycarbonate,metal, or other material capable of bonding to the carbon-fibercomposite of the chassis. The vents may be formed using traditionalmachining methods or through the use of laser drilling, chemicaletching, and/or gradient stamping.

At step 1040, a cutout sized to receive the vent area insert may beformed in the carbon-fiber composite of the chassis. At step 1050, thevent area insert may be inserted into the cutout such that the vent areainsert extends though the carbon-fiber composite of the chassis. At step1060, the vent area insert may be coupled to the chassis. As discussedabove, the multi-layered carbon-fiber composite of the chassis, togetherwith the vent area insert, may be placed in an insert molding machineand bonded using a polymer resin.
